The Hoya Prond Ex 64 67mm filter reduces the amount of light passing through the lens by 6 stops. When shooting video outdoors, you can adjust the shutter speeds to match the frame rate while maintaining the desired depth of field. When filming moving subjects, you can achieve motion blur that makes the image look more cinematic. For photography applications, the filter allows you to use longer exposures or achieve shallow depth of field in bright sunlight.

The ProND EX 64 filter uses Hoya's ACCU-ND technology to prevent color shift in order to provide consistent image quality. ACCU-ND ensures equal light reduction in both the visible and infrared spectrum, so you won’t experience color changes when shooting in varying outdoor conditions. Additional ND filters can be stacked on the front, or you can attach a threaded lens cap or another filter.
